Solve the problem.The table below gives the number of births, in thousands, to females over the age of 35 for a particular state every two years from 1994 to 2010. 
Use technology to find the quartic function that is the best fit for this data, where x is the number of years after 1994. Round to five decimal places.
A. y = - 0.01723x4 + 0.62258x3 - 6.66654x2 + 18.98367x - 43.26566 B. y = 0.01723x4 - 0.62258x3 + 6.66654x2 - 18.98367x + 43.26566 C. y = 43.26566x4 - 18.98367x3 + 6.66654x2 - 0.62258x + 0.01723 D. y = 0.02223x4 - 0.82248x3 + 8.66654x2 - 15.98367x + 41.96566
